Your reservoirs and pumping stations, equipped for the person who goes down.

You operate drinking water, wastewater or industrial structures. In Normandy, we make the composite ladders, hatches, guard-rails and fall protection grids that give access to them: they don’t rust, and check™ tells you at a glance whether the ladder has been inspected. Because in the end, it is often one technician, alone, who goes down.

01 — The moment

At the bottom of a pumping station, a technician, often alone.

A reservoir, a treatment plant, a pumping station. A technician, often alone, opens the hatch with one hand. Below, a drop of several metres, and the fall protection grid, closed. They lift it, and it drops back down once they are through. Then they climb down the caged ladder.

They don’t look at the equipment. They count on it.

Corrosion, the weight of the hatch, the date of the last inspection: at that moment, none of it is on their mind. It is up to you, and to us, to have thought of it beforehand.

02 — Your structures

For every structure, equipment that doesn’t rust.

A closed structure, permanently damp, rarely visited. On metal, corrosion always comes back, and a heavy metal hatch needs lifting equipment. Composite doesn’t rust.

Drinking water

Reservoirs, water towers, treatment plants

What we see
Water intended for consumption, constant humidity, chlorine and ozone in treatment plants.
What composite changes
Our drinking water ladders don’t rust, and their material is ACS-certified. For hatches, a double nested cover with 2-point locking.

Wastewater

Pumping stations, wastewater treatment plants, basins

What we see
H₂S, chlorine, acidic effluents, and a drop of several metres as soon as the hatch opens.
What composite changes
The ladder stays sound, with no repainting. The hatch opens with one hand; below it, the fall protection grid drops back down by itself, so one operator is enough.

Industry

Silos, chimneys, platforms

What we see
Acids, alkalis, solvents, salt spray, and sometimes live equipment.
What composite changes
U90 ladders resist acids, alkalis and solvents. The composite guard-rail is insulating: it can be installed near live equipment, with no equipotential bonding on the profiles.

03 — The inspection

Knowing, before climbing, that the ladder has been inspected.

A ladder that doesn’t rust ends up being overlooked. It looks new, and nobody asks any more whether it has been inspected this year. On job sites, we have seen ladders with no date and no record of inspection. And operators asked us for it: registers, audits, insurers, they wanted simple proof, on the ladder itself.

That’s where check™ came from: our periodic inspection programme for idréva caged ladders. A label fitted once on the ladder, a dated disc every year, a record in the safety register. Your team carries out the inspection, or you hand it to us.

Date passed or disc missing: do not use the ladder.

04 — Who we are

What we can prove, before they go down.

We are idréva, a Normandy-based manufacturer of composite access equipment since 2015. A team that has been working with composite for more than twenty years, in our own factory in Rives-en-Seine since January 2025. You are buying for someone else: you need facts.

50 kg× 32.40 mTHE BAG DOES NOT PASS THROUGH
Diagram of the test: a 50 kg bag, dropped three times from a height of 2.40 m onto a fall protection grid resting on its frame. The bag does not pass through.

This is the impact test from the INRS ED 6076 method, the INRS document on pumping stations. On our fall protection grids and the bars of our hatches, the bag does not pass through. A third-party inspection body has validated it.

The test report is in the Documents section of your portal.

Drinking waterACS

The material in contact with the water is certified.

On our drinking water ladders, it is the material that holds the health conformity certificate, following migration tests in an approved independent laboratory. The certificate ships with every ladder.

Workshop exitSignal™ “Approved” label, with the number, date and signature

Only green leaves the workshop.

Every piece of equipment is inspected in our Rives-en-Seine workshop. Equipment that ships carries the green “Approved” Signal™; on the label, its number, the inspection date and the inspector’s signature. The rest stays with us.

Standards
  • Our ladders comply with EN ISO 14122-4 and NF E85-016
  • Our guard-rail is designed to NF E85-015 and EN ISO 14122

06 — Why we do all this

You buy the equipment. They climb it.

We will probably never meet them. Yet everything starts with them: composite that doesn’t rust, the inspection date on the ladder.
